Air pollution has emerged as a pressing concern in large urban areas, often stemming from sources like intensified traffic and industrial activities within city limits. Addressing this issue requires an understanding of air quality levels, leading to the adoption of low-cost, portable air quality monitoring systems. In our research, we conducted tests using a compact mobile air quality system, SNIFFER 4D (SN), comparing its performance against conventional air quality monitors utilizing standardized methods such as chemiluminescence and spectrometry. The equipment was stationed at the REXDAN research facility situated along one of Galati city's main roads. The primary objective of our study was to evaluate the reliability and suitability of the SN for detailed analysis of trace gases like NO2, O3, and PM10, by cross-referencing data with readings from standard instruments capable of measuring individual trace gases. Data collection spanned from August 17 to August 30, 2023. Our findings indicate that the SN system proved to be a stable and sophisticated tool for conducting high-resolution studies on local and regional air pollution, encompassing pollutants such as NO2, O3, and PM10.
